The document describes the features and characteristics of the IDT723626, IDT723636, and IDT723646 products, including memory storage capacity, clock frequencies, FIFO data buffering, etc.
The document describes the IDT723626/723636/723646 family of monolithic, high-speed, low-power CMOS Triple Bus synchronous (clocked) FIFO memories. These devices support clock frequencies up to 83 MHz and feature read access times as fast as 8ns.
The chips buffer data between a bidirectional 36-bit port (Port A) and two unidirectional 18-bit ports (Port B for transmission and Port C for reception). They offer flexible bus sizing, selectable timing modes including IDT Standard and First Word Fall Through, and programmable Almost-Empty and Almost-Full flags. The devices are available in a 128-pin Thin Quad Flatpack (TQFP) package.
